Our 2 stage gearboxes for planetary use (N2 series) are engineered for extremely efficient (over 95 percent) and greater energy density. This is why they are modular designs that can be assembled according to specific customer needs.
The result of our work is every 2-stage planetary gearbox (N2 series) is built to withstand massive axial and radial loads on the shaft at the output. Additionally, every two-stage gearbox features impressive torque, drive effectiveness, and capacity to load.
Additionally, the effectiveness of a gearbox planetary is due to the distribution of torque in a proportional manner inside this gearing system. This decreases wear and boosts power transfer.
Our 2-stage planetary gearboxes (N2 series) come with steel casings made of ductile iron for strength and resistance to antilock. They also have a case hardening to ensure a superior surface finish that helps to improve the efficiency of every 2-stage gearbox.
We offer a broad selection of planetary gearboxes that are 2-stage (N2 series) to select from. We are a well-known maker of reduction gears for planetary gears.
